Help me settle a debate: Screen time rules for summer

School just ended and my wife and I are already fighting about screen time. She's like "he should only get 1 hour a day" and I'm thinking maybe 2 hours on rainy days is reasonable? He's 8. We've got them in soccer camp and some other activities but it's not like we can fill 8 hours of every day. What's the general consensus here? Are we being too strict, too lenient, or is it a "whatever works for your family" situation?
